SPECIFICATION forming'part of Letters Patent No. 511,954, dated becember19, 1893.

Application filed m 29. 1893.

Be it known that I, ISAAC W. LORD, a citimonga, in the county ofSanBernardino and State of California, have invented a new and Theobject of my invention is to provide a' can with an improved deviceadapted for rapid, safe and convenient filling of lamps and inwhichmeans are provided for a tight A. further object of my invention is toconpact and will therefore be. applicable tocans- A further object is toprovide in connec- I My invention is also applicable to casks,

to hold and discharge liquids.

The accompanying drawings illustrate my invention. a

t Figure 1 is a'side elevation of a can prolar'np. The filler is showninvsection and a Dotted lines indicate the position of the spout sectionof the filler on line 3-3 Fig. 1. Fig.

of my device, a portion of the filler being broken away to show the[arrangement of parts. Fig. 5 is a perspective View of another when themovable collar is turned to out ed the flow of oil from the can. The capof the wallof the fixed collar.

to thefixed collar A and adapted to partially rotate with relation tothe same and provided with the spout opening F adapted and arranged toregister with the discharge opening of the fixed collarat one point inits rotation and to register with the wall of the fixed collar atanother portion of its rotation so that in one position the spoutopening will be closed by the wallof the fixed collar and at anotherposition the passage through the spout opening from the interior of thefixed collar will be unobstructed.

My invention also comprises the combination with the parts abovementioned of a suitable vent tube secured to the movable collar andopening into the inside of the fixed collar and adapted and arranged tobe closed by the wall of the fixed'collar when the movable colhair isturned into position to close the spout opening, and is also so arrangedwith relation to the fixed collar that when the spout opening is thrownopen the passage from thevent into the fixed collaris also opened.

My invention also embraces other features hereinafter more fullyspecified.

In the form shown in Figs. 1, 2 and the vent communicates with theinterior of the fixed collar through a curved tube H apcommunicatingwith the vent hole It through the wall of such fixed collar andcommunicating through such hole with the outer vent tube H which issecured to the loose collar and communicates with the vent hole htherethrough. In this formo'f vent the vent is closed by rotating theloose'collar until its walls close the hole It in the fixed collar, andthe hole h in the loose collar is closed by the In this form I is ascrew cap to form a closure for the outerend-s of the collars. Theflange c which projects beyond the wall of the fixed collar closes the:

outer end of the loose collar and serves to prevent the removal of theloose collar E so long as the cap is screwed in place. To fill a can ofthis description, the screw cap E is removed thus giving access to theinterior of the can. 1

In the forms shown in Figs. 4 and 5 the movable collar E (E") is cappedover by the cap I (1") which is made integral with the movable collarand forms a suitable closure plied to the inside of the fixed collar Aand for the outer ends of both collars. The vent lar A thus to close thevent.

' ,tion thereof is not deemed necessary.

tube H" Fig. 5, extends acrossinside of the loose collar from one wallthereof almost to the outer wall thus leaving a space between the end ofthe tube and the inner face of the wall of the movable collar E" equalto the thickness of the wall of the fixed collar A" and the fixed collarA" is provided with the vent notch J throughout aportion of its outerend opposite the discharge opening 1) so that when the loose collar isrotated to bring the spout Ginto position to register withthe hole D"the inner end of the vent tube I- will be left free so that the air maypass through "the vent tube; and when the collar is turned :to close thehole D", the endof the vent tube 11'' will register with and pressagainst the inside of the wall of the fixedcol- 'lhefixcd col lar ismade of'spring metal and the wall at 'the'portion with which thefree endof the vent tube registers or comes into contact when the outlet isclosed is formed into a spring a which is bout if desired tocause thespring to spring firmly against the inneraend of the vent tube thus toclose it elTect-ually. Suchbend is slight in practice and illustra- Thisspring is shown specifically in Fig. 5.

In the form illustrated in Figs. 4 and 5 the inner fixed collar A (A) isprovided with p the vent tube retaining shoulders or hooks K K beneathwhich the vent tube H (H") tits and comes to rest when the movablecollar is turnedto 'fully close or to fully open the discharge, so thatwhen the movable collar is turned to fully close or to fully open thedischarge, the collar will be locked in place uponthe fixed collar Athus preventing the removal of the collar and holding the contents ofthe vessel secure. The loosecollar can be removed, however, from thefixed collar, by turning it until the vent tube is between the two hooksK K thus to release such tube and allow the loose collar to be drawn 0E.

In order to prevent the vent tube from remaining closed by liquid incase itshould become flooded by the liquid within the can, I provide anauxiliary vent or airhole h near the outer'end of the vent tube,so thatthe air will be admitted to the vent tube and allow the discharge of asmall amount (a drop, for example) of the liquid which may be in thetube when the can is brought upright and this, in flowing .out, willcause the outflow of I the remainder of the liquid which may be withinthe tube. The vent tube extends practically to the end of the spout G(G') so that when the lamp is filled the inflow of air will be stoppedimmediately the liquid rises to the outlet of the tube and spout; or,rather, immediately it rises above the air hole h if such air hole ispresent. When the flow has thus been stopped the can may be raised intoan upright position before further flow will begin. When the How is thusstopped the loose collar is turned to close the outlet and the can isready to be stowed away. The in-' nor end of the vent tube is at theside of the collar opposite the spout opening so that when the filler isin use to discharge the oilor other liquid the inlet for admitting theair into the can will be above the spout opening so that the air will beadmitted therethrough to supply the vacuum resulting from the dischargeof the oil from the can.

Now, having described my invention, what I claim as new, and desire tosecure by Letters Patent, ise 1. The combination of the fixed collarprovided with the lateral discharge openiugand provided with the venttube retaining shoulder; the loose movable collar fitted to the fixedcollar and adapted to partially rotate with relation to the same andprovided ,with the spout opening and adapted and arranged to registerwith the discharge opening of the fixed collar atone point-of itsnotationand to register with the wall of the fixed collar at anotherportion of its rotation; the vent tube secured to the movable collar andopening into the inside of the fixed collarandadapted to fit beneath thevent-tube retaining shoulder, and a suitableclosure for the endsot-thecollars.

2. The combination of the .fixedcollar provided with the lateraldischargeope-ning, and with the vent tube notch, the vent tube closingspring and the vent tubevretain-ing-shoulder; the loose movable collarfitted to the fixed collar and adapted to partially rotate with relationto the same and provided with the spout opening and adapted andarrangedto register with the discharge opening of the I fixed collar at onepoint in its rotation and to register with the wall of the fixed collarat another portion of its rotation; and the vent tube secured to themovablecollar andopening into the inside of the fixed collar and adaptedto fit beneath the vent tube retaining shoulder and engage the vent tubeclosin g spring, .anda suitable closure forthe outer ends of thecollars.

3. A lamp filler comprising the fixed and movable collars and thesuitable closure for the outer ends thereof and provided with the spoutopening and the spout and with the vent tube fixed to the spout, andhaving its interior opening arranged within the collars opposite thespout opening.
